The TweetDeck app does let you schedule your tweets for later posting, as do similar social media management programs like Hootsuite. If you have composed your posts ahead of time, you can go back and edit them before they are scheduled to publish.

Iconfactory’s Twitterific 5 for iOS is one app that tries to make fixing an errant post a little easier (a $5 Mac desktop version of the app is also available but development stopped in 2013 with version 4.5.1). The iOS app has a “Delete and Edit Tweet” command that deletes your original post and copies the text into a new, pending one that you can quickly edit. Once you have finished editing, you can post the new version, but it will carry a new time stamp; favorites and retweets from the original message will be lost.
